Author: systemvipers Love these fittings, i was a big fan of hte high flow but I am now switching to the fat boys.
these are sweet fittings...
Author: uh8medoncha I bought 4 of these to replace a couple of the older high flow barbs and they are fantastic. The O-ring capture seal keeps the O ring from herniating under uneven pressure or to my direct down force. I am replacing all of my barb with the asap!
Author: Tek The only thing I dont like about these barbs is the short length of the threaded portion. I dont feel like I am getting the same quality seal as perfect seal or high flow barbs. Especially when you put them into an acrylic hole such as a res.
